AXLE-BOX.

To all whom it may concern Be it known that I, JOHN J. GILRoY, a citizenof the United States, residing at Pittston, in the county of Luzerne andState of Pennsylvania, have invented new and useful Improvements inAxle-Boxes, of which the following is a specification.

The invention relates to a construction of axle box, wherein specificprovision is made for delivering the lubricant directly on to the uppersurface of the contained axle.

The main object of the present invention is the provision of an axle boxin which a lubricant chamber is provided above the bearing block andfrom which the lubricant is delivered directly on to the block andthrough suitable channels in the latter to the axle, the construction ofthe box providing for taking up the surplus oil or lubricant andire-delivering it to the axle.

The invention in its preferred form of details will be described in thefollowing specification, reference being had particularly to theaccompanying drawings, in.

which Figure 1 is a plan of the improved axle box. Fig. 2 is a frontelevation of the same. Fig. 3 is a section on line 33 of Fig. 1. Fig. 4is a section on line 1-4: of Fig. 1. Fig. 5 is a plan of the bearingblock. Fig. 6 is a front elevation of said block.

Referring particularly to the accompanying drawings, the improved axlebox, which aside from the details hereinafter mentioned, may be of anypreferred or usual construction, includes what may be generally termed abody 1 open as usual at one side for the introduction of the axle 2, andclosed at the opposite side to completely house the free ends of theaxle. Centrally of the upper portion of the box, there is formed orprovided what may be termed an oil reservoir 3, the same extendingtransversely through the box being closed at the rear end and open atthe front end through comparatively elevated reduced port 1 preferablyformed through an enlargement or extension 5 of the box, the port 1serving as a filling opening and by reason of the overhang of the upperportion of the enlargement, in a measure protected against entrance offoreign matter. A bottom of the lower reservoir immediately adjacent itscommunication with the port 4 is formed with a pocket Specification ofLetters Patent.

6 adapted to receive packing or the like, whereby to preventdisplacement of the oil in the reservoir through jar incident to travelof the car. The bottom wall of the reservoir 3 is formed with an opening7 through which the lubricant from the reservoir is delivered.

. Movably mounted in the box 1 in the usual manner is a bearing block 8,said block in this mstance being formed on its upper surface with acomparatively shallow recess 9 to which oil is delivered from the openlngs 7, the block being formed within the plane of the recess with anopening 10 extending vertically therethrough directly to the axle withradiating channels 11 in communication with the recess and leadingtherefrom throughout the top and side surface of the block. By thismeans the oil delivered from the reservoir 3 is directly transferred tothe axle and on the upper surface thereof, as will be evident.

The box 1 in both directions beyond the bearing block space is formed toprovide packing chambers 12, the forward wall of these chambers beingformed with openings through which packing may be introduced. The lowerportions of the chambers lead to and terminate adjacent the axle belowthe lovsfir outer edge of the bearing block, as at In use the oil fromthe reservoir finds its way directly on to the top of the axle throughthe opening 7 the recess 9 in the bearing block and the opening 10therein, excess oil being taken up by the packing in the chambers 12,finally reaching the bottom of said channels where it is stored orretained and redelivered to the axle for lubrication. The axle box isprovided with the usual bolt holes 13.

What is claimed is An axle box formed with an oil reservoir in its upperportion, a bearing block operative within the box and arranged beneaththe reservoir, said bearing block having a shallow recess to receive oilfrom the reservoir, an opening leading from the recess to deliver oiltherein to the axle, packing receiving chambers arranged on oppositesides of the bearing block and terminating adj acent the axle, thebearing block having the lateral channels in the upper and side surfacesthereof leading from the recess in said block to the packing chamber,said bear- Patented Apr. 27, 1915.
